what do y'all think of paintball, as a training exercise ? certainly not as instantaneous as actual bullets, you can see them whizzing by, but the level of realism is uncanny these day, there are paintball ar's and paintball ak's everywhere. I just picked up a lovely tippmann 98 paitnabll "marker", and I'm taking out out in the woods with some buddies. What do you guys think ? Ever heard of this ?
